Had to buy it again

I used this app for years. There was a rebranding and I could no longer install it on a new iPhone, so here we go - double or nothing. Developer did not answer my email, I hope he is well and continues to develop it, maybe update the interface with new colors/graphics, make it safer to import / export bookmarks/notes (in a playlist?) I lost notes a few times... fabulous essential app for me even as it is.

Best audiobook player I’ve tried!

I’ve been using this app for 8 years, it’s the best audiobook player you can get on the market. It has unique ability to repeat playing a book after the end. You can’t find this feature in any other audiobook player. The settings also have many useful features for both music & audiobook. Will buy again (if next version available)

My main Go-To Audio app!

Most other audiobook apps have much thicker speed up granularities (typically 25%). Unfortunately, this is not helpful with certain readers (depending on accent and natural reading flow). I love that I can control to a 5% granularity.

I also appreciate the ability to configure multiple go-back and jump-ahead values. My absolute favorite audiobook app!
